Kyle Teegarden has me wondering:
Power BI is a widely used, interactive visualization tool capable of querying a variety of SQL-powered back ends. To accelerate these queries, and provide an even more responsive Power BI user experience, we’ve developed Redis SQL ODBC.
Redis SQL ODBC is a native ODBC driver that lets you seamlessly integrate Azure Cache for Redis Enterprise and Enterprise Flash tiers with Power BI. This may dramatically improve your Power BI query response times.
Knowing that the intent of Redis is individual point lookups, this was a bit surprising. Doing the queries over secondary indexes does help square that circle, however.
